IMPROVEMENTIN TAPS FOR BARRELS.

Specification forming part of Letters Patent N0. 203,706, dated May 14, `1878; application tiled August 9, 1877.

To all whom it may concern: k

Be it known that we, ROBERT H. BYRNE and EDWARD D. KNIGHT, both of Camden, in Camden county, New Jersey, have invented an Improvement in Stop-Cocksfor Barrels, of which improvement the following is a specification:

Our invention relates to stopcocks such as have metallic bun gs permanently iixed in the heads of barrels, faucets being attached to or detached from such cocks by screw-threads, as desired.

The object of our invention is to construct the cock in such form that, while faucets may be attached thereto with the utmost facility, the cocks shall be freed from leakage at all times.

Our said invention consists of, rst, a beveled or valve-faced shoulder formed on the faucets neck, near its extremity; second, a correspondingly-beveled recess or valve-seat formed in the bung; third, a beveled or valvefaced ange attached to the inner end of the tapper; fourth,`a shoulder on the outer end of the tapper; fifth, a shoulder and a beveled recess in the inner end of the body of the bung,

the several parts being constructed and com-- bined as hereinafter set forth.

In the drawings, Figure l is a longitudinal; section of the bung and tapper as applied to the head of a barrel, the faucet being shown in elevation attached. Fig.2 is a longitluilinal` section of the bung and tapper in the relative positions these parts hold toward each other when the orifice for the. escape of liquids isy closed. Fig. 2 also shows, in like section, the

neck of the faucet'detached. Fig. 3 is a front elevation ofthe bung and tapper.

Like letters designate like parts in the sevof a barrel. B represents the tapper, which is a hollow cylinder with a shoulder, C, on its K outer end, and a beveled or valve-faced flange, D, on its inner end. E is a shoulder formed in the body of the bung. corresponding in depth with the shoulder O of the tapper. F is the faucet, having the beveled or valvefaced shoulder F' formed on its neck. G is a recess in the head of the bung. The recess G is beveled to correspond with the shoulder F', the two, when brought into contact, forming a valve-joint.

Projecting from the neck of the faucet are pins H, differing in diameter, which are inserted into corresponding holes I in the shoulder C ofthe tapper. i

When the cock is closed the bevel-faced liange D is in close contact with the correspondingly-beveled inner end of the bung, as shown in Fig. 2.

When it is desired to tap a barrel the faucet is applied to the cock by inserting the pins H in the holes I, and then, by turning the faucet, screwing the tapper B until the bevel-faced shoulder F comes into close contact with the beveled sides of the recess G in the bun g, thus opening the cock and permitting liquids to dow out through the tapper into the faucet.

The shoulder C prevents the tapper from getting beyond the reach of the faucet-pins H by any accidental turning of the tapper, such as might be occasioned by the shaking or rolling of the barrel when the tapper consists of a plain cylinder without a shoulder, as shown in Zollers Patent No. 163,717, of the date of May 25, 1875. The shoulder G also acts as an additional means to prevent leakage.

We claim- The tapper B, constructed with the bevelfaced flange D on its inner end and the shoulder C on its outer end, in combination with the bung A, constructed with the shoulder E and the beveled seat for the iiange or valve D, in the manner and for the purpose substantially as set forth.
